I know the left bar verticly is the RPM but when u go from left to right is what ??

 

That is the amount of load on the engine. MBar is vacuam until you get to were it says .5 then that is going into boost

 

Top number is just a number denoting which column you're in. As it shows you down at the bottom, the second colum is your reading from the MAP sensor.

 

I know that but i do not understand the units like when im at 6000 rpm and i move over to the right how do i correspond with the PSI like say im at 6000 rpm and 8psi of boost the map would be in the high cam but on the chart were to the far right cause its like mBAR 4.0

 

Oh i thikn i figured it out lol I moved the chart over this is what i get is the number indicate PSI or ??? The ones highlited in red from 10 to 16

 

Click on the seperation bar at column 11 and drag it to the right so you can make the table larger.

You got it. Columns 10 through 16 indicate 0.5PSI to 28PSI.

 

Coo now i understand it i did not see the coloums from 11 on cause i could not see them.

 

Cause if you look at 10 to 16 notice that at 6000 above the map goes down leans out???

It should lean out a bit on the top end, do you have a wideband on the car? You aren't doing any tuning without one I hope.

As your torque is falling off and/or staying linear

 

I orig got S30 cause i was tired of the tune. I just slapped some base maps used the EGT gauge to make sure they did not go past 1400 and i drove it all last year when i was in the millitary driving 1500km per weekend. This year im gonna get a Wide Band im looking at the PLX300 so i can tune this thing properly.

Whats a good wide band for the S300 the AEM or the PLX300?

 

i have the plx m-300 and love it

 

I love my PLX M-300 and I wouldn't trade it for anything else.
